@JvmStatic @Provides @Singletonn fun providesHandler( ): SomeHandler = HandlerObject.init() This is the provider, i have inside the some module and that module is sits in the application component and it's singleton. I know that dagger generates all the module providers classes at compile time, as gets the instance dependency through the

get()

overriden method in the class. As all classes required for the DI graph are created at compile time. I was wondering when the actual creation of the object happens, when

get()

is actually called. Does it gets called and object is created when it's requested through

@inject

or happens at compile time and just returns when

@inject

gets called.

If you inspect Dagger’s source code, you’ll find a lot of

Provider

classes. These are invoked when the instance is supposed to be injected somewhere, and only then objects get created. So your

HandleObject.init()

will be called only when it’s injected, not before. Anyway or happens at compile time doesn’t make much sense, as objects aren’t really created during compilation

Thanks for answering @wasyl My thought was same as it should be created only when the dependencies are requested though,

field

or

constructor

or any other injection types. I am stuck with a bug and just wanted to make sure. Thanks again!
